WASHING-MACHINE.

Specification of Letters Patent.

latented Dec. 2d, i918.

Application filed December 6, 1915. Serial No. 65,291.

To ZZ whom t may concern.'

Be it known that l, Arens C. CARLSON, a citizen 0f the United States ofAmerica, residing at Butler, in the county of Butler and State ofPennsylvania, have invented new and useful Improvements in Washing-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform part of this specification.

The primary obj ect of my invention is to provide means whereby thewater used in a washing machine may be conveniently kept at atemperature which shall facilitate and improve the work usually done bysuch machines. As such a device l provide water heating means that issimple in construction, may be easily attached to the machine and may bekept in operation without continued attention on the part of theoperator.

l will now describe my invention so that others skilled in the art towhich it appertains may understand and construct the same, it beingpremised however that changes may be made in the structures shown anddescribed without departing from the invention claimed.

Figure l is a fragmentary view of a rotatable wash tub and its support,showing my invention applied thereto:

Fig. 2 is a fragmentary view showing a modified form of heating means,and

Fig. 3 is a fragmentary view of the inside of the tub bottom showing thetank connection with the tub bottom.

Referring t0 the drawing, the reference numeral 2 indicates the tubportion of an ordinary washing machine of the type in which the tubitself is rotatable, as for instance, for coperation with a stationarydasher. Communicating with the tub through the bottom wall 3, is a watertank i4. This tank, which is preferably constructed of thin sheet metalto obtain the maximum conductivity of heat, and is relatively small anddrum-like in appearance, has .its connection with the bottom of the tubby means 0f a pipe 5 carrying a flange or head 6 which abuis against theunder face of the tub body and cooperates with a top plate 7 throughconnecting bolts or fastening means 8 to effect a proper seal. The platemember 7 is preferably provided with a plurality of perforations 7a,which, while allowing for communication between the tub chamber andtank, are of such size as to prevent small articles in the tub, fromworking down into the mouth of the pipe 5. The tank is also providedwith a capped drain outlet 9.

ln order not to interfere with the action of the rotating tub, the pipe5 passes through an opening 14 in the stationary support or housing l5of the washing machine; the opening 14 being of ample size t0 allow thepipe 5 to rotate freely with movement of the tub 2 upon the ball-bearing16.

Disposed. beneath the tank 4 is a gas burner 10 supported by a standardor bracket ll that is carried on a suitable base board l2 mounted acrossthe foot rods or braces 13, as clearly shown.

lt will of course be understood that with water in the tub, a portion ofit will pass to the tank. Any air that may be imprisoned in the tank,incident to sudden charging of the water in the tank may be freed byopening the drain 9 or it will be released upon agitation of the waterset up in the washing of the clothes. Vhen the tank has thus been filledwith water, the gas burner l0 or oil burner 17 (Fig. 3) disposed beneaththe tank, may be lighted. The heat thus generated quickly penetrates thethin metal of the tank and brings the temperature of the water thereinto a high point. municates its heat to the larger bodv of water in thetub, and the steam thus generated greatly facilitates and improves thework done by the washing machine.

Having thus described my invention, what l claim and desire to secure byLetters Patent is:

In combination with a rotatable wash tub and its support, a heatercomprising a tank disposed below the bottom of said tub and below thetop of said support, and a vertical pipe connected and communicatingwith said tank centrally of the top thereof and connected andcommunicating with said tub centrally of its bottom wall, said supportbeing provided with a hole permitting the passage of said pipe, saidtank being rotatable with said tub, and a burner disposed below saidtank and stationary in respect to said support.

This wat-er in turn quickly com- In testimony whereof I have hereuntoset y my hand. ANGER C. CARLSON.
